Using 'window' with a local variable for global access in JavaScript
global-variables, javascript, variables
Solution
var myNameSpace = { };
myNameSpace.localVar = window.localVar = 'foo';
You can't access another object when defining the key from another object, like you tried. But you certainly can create multiple references/assignments to the same value, like shown above.
However, be aware that we assigning a primitive value in this case, that means, `window.localVar` and `myNameSpace.localVar` will hold their own unique value. Any change will not reflect on the other side.
Problem
I'd like to access a local variable globally (without changing the namespace or location of the variable). I read that I could use 'window.', but it's not working: ``` var myNameSpace = { window.localVar : 'foo' }; alert(window.localVar); // Not working ``` JSFiddle Can something like this work? Also, I've read about the risks of global variables. If I'm nearly certain a variable's name isn't at risk to be reused, is it safe? ``` $myTotallyUniqueVarName ```
